Abstract

In an automated speech recognition system (50), a microphone (52) records a keyword spoken by a user. A front end (62) divides the recorded keyword into a plurality of subunits, each containing a segment of recorded audio, and extracts a set of features from each of the plurality of subunits. A decoder (64) assigns one of a plurality of content classes to each of the plurality of subunits according to at least the extracted set of features for each subunit. A quality evaluation component (66) calculates a score representing a quality of the keyword from the content classes assigned to the plurality of subunits.
